We are thinking about going to Orlando from Baltimore on Dec 27-Jan 3rd. It must be a popular week because the airfare is so high it will prevent us from going at all. (apprx. $288 per person 1 way). For all of you experts on airline rates, when should I watch to see if they will come down for that week if at all? Airtran and Southwest are comparable. Any tricks or tips would be appreciated!! Thanks so much!
